Installing the Equipment

2

 

This chapter explains how to install the premises equipment. It begins with general guidelines to consider before installation, followed by an example configuration. It ends with step-by-step instructions for connecting and testing the components.

IMPORTANT:

Before installation you should review Forms A and B of the System Planner to identify the type of equipment that should be connected to the extension jacks for your system.

Terminology

The following terms are used in this chapter. In addition, you may wish to review the “Terminology” section of “About This Guide, ” which defines basic terms used throughout this guide, or the Glossary, which defines all terms.

Backplane

The bottom and rear portion of the plastic housing that makes

 

up a carrier. The backplane distributes power to the

 

premises equipment, and has slots where the modules are

 

installed.

Carrier

Molded plastic housing, made up of a backplane and cover,

 

which holds the equipment controller modules. Your

 

configuration contains at least the primary carrier and can be

 

expanded to include an expansion carrier.

Combination extension

An extension that has two devices connected to it using a special connector called a bridging adapter. Combination extensions can connect two industry-standard devices or an industry-standard device and an MLS- or MLC-model phone, but not two MLS- or MLC-model phones.

AT&T II, a pivotal case in the landscape of telecommunications regulation, emerged from the expansive antitrust actions against the American Telephone and Telegraph Company (AT&T). Following World War II, AT&T had established itself as a telecommunications behemoth, monopolizing the market. The ramifications of this dominance spurred a significant shift in regulatory measures, leading to the dissolution of the Bell System in 1984, which consisted of AT&T and its regional operating companies.

One key feature of AT&T II is its emphasis on promoting competition in the telecommunications sector. The court's decision aimed to dismantle the monopolistic practices that had stifled innovation and restricted consumer choice. By encouraging competition among various service providers, the ruling paved the way for an environment where new technologies could flourish.

The technologies that emerged post-AT&T II significantly transformed the telecommunications landscape. The introduction of new digital switching systems allowed for improved call quality and increased network efficiency. The evolution of fiber-optic technology also played a crucial role, enabling faster transmission speeds and greater data capacity. Moreover, innovative services, such as mobile telephony and broadband internet, proliferated as competition increased.

Another characteristic of AT&T II is its focus on accessibility and consumer protection. The ruling mandated that telecommunications services be available to a broader swath of the population, ensuring that underserved communities had access to essential communication services. This shift not only democratized access but also laid the groundwork for the modern internet revolution, fostering the growth of the digital economy.

The impact of AT&T II can also be seen in the regulatory frameworks that followed. The Federal Communications Commission (FCC) adopted policies aimed at enhancing market transparency and ensuring fair practices among competitors. These regulatory changes helped to create a more equitable playing field, allowing smaller companies to compete against established giants.

In summary, AT&T II marked a turning point in telecommunications history, characterized by a focus on competition, technological advancements, and consumer protection. The dissolution of AT&T's monopoly allowed for the rapid evolution of technology and services, ultimately benefiting consumers and fostering an environment ripe for innovation. This ruling not only redefined the telecommunications industry but also set a precedent for how markets are regulated in the United States.
